Answer:

12 square ft.

Step-by-step explanation:

A= l*w.

We already have the area so we have to work backwards.

144= l*w.

144/2= 12

let's plug it in.

144=12*12

The school that Mary goes to is selling tickets to a spring musical. On the first day of ticket sales

andrezito [222]

Answer:

The cost of one adult ticket is $13, and the price of one student ticket is $4.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the cost of an adult ticket

y is the cost of a student ticket.

6 adult tickets and 1 student ticket for a total of $82

This means that

$6x + y = 82$

$y = 82 - 6x$

The school took in $51 on the second day by selling 3 adult tickets and 3 student tickets.

This means that

$3x + 3y = 51$

Simplifying by 3

$x + y = 17$

Since $y = 82 - 6x$

$x + 82 - 6x = 17$

$-5x = -65$

$5x = 65$

$x = \frac{65}{5} = 13$

$y = 82 - 6x = 82 - 6*13 = 82-78 = 4$

The cost of one adult ticket is $13, and the price of one student ticket is $4.

The gcd of two numbers is 17 and their lcm is 204. one of the numbers is 68. find the other number.

KiRa [710]

$x\cdot y=GCD(x,\ y)\cdot LCM(x,\ y)\\\\\text{We have}\\\\x=68,\ GCD=17,\ LCM=204.\\\\\text{Substitute:}\\\\68y=(17)(204)\\\\68y=3,468\qquad\text{divide both sides by 68}\\\\\boxed{y=51}\\\\Answer:\ \boxed{\text{The other number is 51.}}$
